Beryllium är ett grundämne som tillhör gruppen alkaliska jordartsmetaller.Dess kemiska egenskaper avviker dock en del från de övriga alkaliska jordartsmetallerna, så att den i vissa avseenden påminner om aluminium.Beryllium är ett tämligen ovanligt grundämne, men koncentreras i vissa mineral, speciellt beryll (genomsnittsformel Be 3 Al 2 (SiO 3) …
Berylliosis (beryllium disease) is chronic inflammation in your lungs due to inhaling fumes or dust containing beryllium. Beryllium is a metal used to manufacture many different products. Beryllium disease is an immune system response, which means only people who have an allergy to beryllium (beryllium sensitization, or BeS) develop …
Beryllium is the lightest of all the metals on the periodic table, with an atomic weight of 9.012 g/mol and an atomic structure made up of 4 protons, 4 neutrons, and 4 electrons. Its melting point is 1287°C, and its boiling point is 2970°C. It is a very dense material, with a density of 1.85 g/cm3.
Today, the extraction of beryllium begins with the mining of raw materials (bertrandite ore and/or beryl ore). Beryl ore is melted in industrial furnaces, solidified and crushed, then treated with sulfuric acid to produce a water-soluble sulfate. Bertrandite ore is crushed, made into slurry and treated with sulfuric acid to form a sulfate.
Beryllium (Be) Beryllium is the 4th element in the periodic table and has a symbol of Be and atomic number of 4. It has an atomic weight of 9.01218 and a mass number of 9. Beryllium has four protons and five neutrons in its nucleus, and four electrons in two shells. It is located in group two, period two and block s of the periodic table.
Beryllium is a silvery-white metal. It is relatively soft and has a low density. Uses. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.
INTRODUCTION. Beryllium (Be) mostly occurs naturally as beryllium aluminium silicate (beryl), 3BeO.Al 2 O 3.6SiO 2.As a naturally occurring element, beryllium is present in rocks, coal and oil, soil and volcanic dust.[] The element forms a light, hard, noncorrosive metal.[] Although beryllium was discovered in 1798, it only became commercially …
This standard means this beryllium standard, 29 CFR 1910.1024. ( c) Permissible Exposure Limits (PELs) —. ( 1) Time-weighted average (TWA) PEL. The employer must ensure that no employee is exposed to an airborne concentration of beryllium in excess of 0.2 µg/m 3 calculated as an 8-hour TWA. ( 2) Short-term exposure limit (STEL).
Where appropriate, based on the beryllium content of the material, employees and employers may be able to assess whether surfaces are visibly clean as a practical guide to determine the effectiveness of a housekeeping program. ... Procedures for removing, laundering, storing, cleaning, repairing, and disposing of beryllium-contaminated …
2. Clothing issued to workers by the employer when machining beryllium copper helps keep the dust confined to the worksite; laundering work clothing at the worksite, compulsory showers, and special lockers may be necessary under conditions of possibly high exposure. 3. Wet operation is somewhat safer than dry machining operations.
Beryllium work area means any work area where materials that contain at least 0.1% beryllium by weight are processed either: (1) during any of the operations listed in Appendix A of this Standard; or (2) where employees are, or can reasonably be expected to be, exposed to airborne beryllium at or above the action level.
Beryllium (atomic number, 4; relative atomic mass, 9.01) is a metal, which belongs to Group IIA of the Periodic Table. The oxidation state of beryllium compounds is +2. Selected chemical and physical properties of beryllium, beryllium–aluminium and beryllium–copper alloys, and various beryllium compounds can be found in the …
Today, beryllium is primarily obtained from the minerals beryl (Be 3 Al 2 (SiO 3) 6) and bertrandite (4BeO·2SiO 2 ·H 2 O) through a chemical process or through the electrolysis of a mixture of molten beryllium chloride (BeCl 2) and sodium chloride (NaCl). Jefferson Lab, U.S. Department of Energy. From the Greek word beryllos, beryl; also ...

Dry hand sanding or filing of beryllium must either be performed inside a ventilated enclosure or performed completely wetted or submerged. Parts and other contact materials must be cleaned before removing from the ventilated enclosure or immediately after wet processing. Compressed air must not be used to clean parts.
